Question

Think of a number, add 2 to it and then multiply the sum by 6, the result is 42.

Answer 1

Given :

• Think of a number
• add 2 to it.
• multiply the sum by 6
• The result is 42

Solution :

Let the number given to think be x.

So, now we add 2 to x. So, it will be x + 2

Now, we will multiply the sum by 6. So, it will be 6( x + 2).

Now, according to the question the result will be 42. So, the equation we get is:

→ 6( x + 2) = 42

→ 6x + 12 = 42

→ 6x = 42 - 12

→ x = 30/6

→ x = 5

So, the number we thought was 5.

Now let's verify our answer :

According to our answer x = 5

So,

→ 6( x + 2) = 42

→ 6(5) + 12 = 42

→ 30 + 12 = 42

→ 42 = 42

.°. LHS = RHS

Hence, verified

So, the equal we got = 6( x + 2) = 42

And the value of x = 5.
